Step-by-step explanation:
Amelia got 56% of 75 so
(56/100)*75=(56*75)/100=4200/100=42
Hayden got 8/15 of 75 so
(8/15)*75=(8*75)/15=600/15=40
and Sophie that got 43 out of 75
so we see that Sophie got the highest points.
3(x+4)=1/2x-8 that's your original equation. If you read through the problem as you look at my work, you will see it matches up as you read it out loud and see my equation.
to solve, first distribute.
3x+12=1/2x-8
next you need to subtract 1/2x from both sides. this is using the identity property of addition.
2.5x+12=-8
next, subtract 12 from both sides. this demonstrates the identity property of subtraction.
2.5x=-20
next, divide by the coefficient of x (which is 2.5) to find the value of x, your variable.
x=8. you're done. hope this helped :)
Step-by-step explanation:
Given that,
For 4 weeks in June, Cameron biked 3 1/4 miles each week and swam 2 1/2 miles each week.
For 3 weeks in July, he biked 4 3/4 miles each week and swam 3 1/2 miles each week.
We need to find how much greater was the total distance Cameron bike and swim in July compared to the total distance he bike in swim in June.
In July, total distance is ,
In June, total distance is :
Hence, in June total distance is 23 miles and in July total distance is 24.75 miles.
I think it should be 7g?
Not sure tho
Answer:
Step-by-step explanation:
f(2) = 2^3 - 4(2)^2 = 8 - 4(4) = 8 - 16 = -8
g(-8)= 4(-8) + 5 = -32 + 5 = -27
C is the answer
